🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and support the front

• Place wheel chocks at the rear wheels.
• Lift the front with a floor jack (rated 3-ton minimum).
• Set the truck down onto jack stands (rated 3-ton minimum) under the frame.
• Give the truck a gentle push to confirm it’s stable.

Step 2: Remove the lower shield (if equipped)

• Remove the fasteners using a 10mm socket and ratchet.
• Pop plastic clips (if present) with a flathead screwdriver.
• Set the shield and fasteners aside in a small pile so nothing gets lost.

Step 3: Drain the engine oil

• Place the drain pan (7-quart minimum) under the oil pan drain plug.
• Loosen and remove the drain plug using a 15mm socket, ratchet, and extension (3-inch).
• Let the oil drain until it slows to an occasional drip (usually 5–10 minutes).
• Reinstall the drain plug and tighten with a torque wrench (10–100 ft-lbs range): Torque to 25 Nm (18 ft-lbs).

Step 4: Remove and replace the oil filter

• Move the drain pan (7-quart minimum) under the oil filter area (some oil will spill).
• Remove the oil filter using an oil filter wrench (band or cap style).
• Wipe the engine’s filter sealing surface with shop rags.
• Put a light film of new oil on the new filter’s rubber gasket (dip a finger into fresh oil).
• Install the new oil filter by hand until the gasket contacts, then tighten: Torque to 18 Nm (13 ft-lbs) using the oil filter wrench (band or cap style) (or hand-tight plus about 3/4 turn if you can’t fit a torque wrench).
• Make sure the old gasket didn’t stick.

Step 5: Reinstall the shield (if removed) and lower the truck

• Reinstall the shield fasteners using the 10mm socket and ratchet.
• Lower the truck from the jack stands (rated 3-ton minimum) using the floor jack (rated 3-ton minimum).

Step 6: Refill with new oil

• Open the hood and remove the oil fill cap.
• Place a funnel in the fill hole.
• Pour in Engine oil (SAE 5W-30 full synthetic, dexos1) (start with about 5.5 quarts).
• Reinstall the oil fill cap.

Step 7: Start, check for leaks, and verify the oil level

• Start the engine and let it idle 30–60 seconds.
• Check underneath for leaks at the drain plug and oil filter using safety glasses.
• Shut the engine off and wait 5 minutes.
• Check the dipstick, then top off as needed using the funnel (add small amounts until at the full mark).
• Wipe any spilled oil with shop rags.

Step 8: Reset the Oil Life Monitor

• Turn the key to ON (engine off).
• Use the steering wheel buttons to open the Driver Information Center.
• Navigate to Vehicle Info > Oil Life.
• Press and hold SET/CLR until it resets to 100%.
